 * Smarty plugin

 * Type:     function
 * Name:     random
 * Purpose:  output a random number between $varIn and $varOut:
 *    {random in=$varIn out=$varOut}
 *    If you want to assign the random number to a variable
 *    instead of displaying it, you must write:
 *    {random in=$varIn out=$varOut assign=yourVar}
 *    Where yourVar can be anything. Then you'll get
 *    $yourVar equal to a random number between $varIn and $varOut.
